[Twisted-Python] Problems with trial in 8.0.1

[Brian Granger]

Hi,

I just got around to installing twisted 8.0.1 (from the tarball) and I
see the following when I run

trial twisted

Traceback (most recent call last):
  File "/usr/local/bin/trial", line 5, in <module>
    pkg_resources.run_script('Twisted==8.0.1', 'trial')
  File "/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/pkg_resources.py",
line 448, in run_script

  File "/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/pkg_resources.py",
line 1160, in run_script
    execfile(script_filename, namespace, namespace)
pkg_resources.ResolutionError: No script named 'trial'

I did not use setuptools to install twisted (just plain old python
setup.py install).  Any ideas?
